Can pulpitis cause headaches?
Pulpitis can cause headaches. Pulpitis is caused by the progression of dental caries, and it is the natural outcome of dental caries. Bacterial infections cause the dental nerve to become purulent and necrotic, or cause an acute inflammatory response in the dental nerve, which is pulpitis. The clinical symptoms of pulpitis include pain stimulated by hot and cold, which becomes more noticeable when consuming hot or cold food, or the pain may be non-localizable, which is also a typical symptom of pulpitis. It often happens that if one tooth suffers from pulpitis, the pain may occur in teeth on the same side of both the upper and lower jaws, and it is unclear which specific tooth is causing the pain, due to the non-localizing nature of pulpitis. Additionally, sometimes the pain may radiate towards the ear causing headaches, which is why pulpitis can lead to headaches.
Can periodontitis be cured?
Periodontitis is divided into early and late stages. Early periodontitis can be cured, while late periodontitis is difficult to treat and may require tooth extraction if severe. Periodontitis is an inflammatory, destructive resorption that occurs in the periodontal supporting tissues. There are usually significant amounts of dental calculus and plaque around the teeth. The initial treatment involves removing these through teeth cleaning. After cleaning, applying medication through rinsing around the gums can be helpful, and in many cases, this can lead to a cure. Generally, early periodontitis does not involve noticeable absorption of the alveolar bone. However, in advanced stages, the formation of periodontal pockets and absorption of the alveolar or jaw bone represent severe manifestations of periodontitis. If it is difficult to maintain or restore oral health through basic treatment in such cases, tooth extraction may be necessary.
Will children's cavities grow new teeth?
Children's cavities can also regrow new teeth. Cavities, also known as dental caries, refer to the destruction of hard dental tissues under a bacterial infection. It is crucial to treat children's cavities early, otherwise, they may affect the underlying new teeth. If the cavity reaches the level of periapical inflammation, meaning the dental pulp tissues become pus-filled or necrotic, and gum abscesses appear, it could cause the newly emerged teeth to develop caries. Sometimes, it may also lead to abnormal eruption pathways of the new teeth, such as abnormal eruptions on the lip side or cheek side, resulting in misaligned teeth, which can impact the arrangement of the child’s primary or permanent teeth.
Can tooth decay heal by itself?
Cavities are a type of dental hard tissue defect caused by bacterial infection, and represent a chronic, progressive, destructive disease. In the early stages of a cavity, if only the enamel layer is involved with simple demineralization of the tooth, then remineralization treatment can be conducted. This scenario is the only reversible one where the cavity can heal itself. If the cavity progresses to the dentin layer, then it cannot heal by itself and requires timely intervention by drilling to remove the decayed part and performing a filling treatment. If the infection is not controlled in time, bacteria can further cause the dental nerve to become purulent and necrotic, leading to symptoms of pulpitis or apical periodontitis. In such cases, timely root canal treatment is necessary.
Why do cavities turn black?
Cavities generally appear black, while normal teeth are white. The structural changes in the dental tissues due to bacterial infection cause the hard tissues of the teeth to demineralize, enlarging the internal spaces of the teeth. This can cause cavities to appear black under the refraction of sunlight, resulting in a black appearance. Additionally, after the deterioration of the tooth due to decay, the breakdown of the hard tissue allows food residues or plaque to enter the cavities, which can also cause the cavities to turn black. This situation requires early dental filling to remove the decayed parts, followed by root canal treatment, otherwise it can lead to pulpitis, causing tooth pain.
Does root canal treatment for pulpitis hurt?
During the treatment process of pulpitis root canal, there will be some pain. Pulpitis is caused by bacterial infection that leads to inflammation of the dental nerve, and the pain is very intense. First, the ocular nerve should be treated, and pulp extraction can be performed under local anesthesia. During this stage, if anesthetic is administered, the pain will not be so apparent. If no local anesthesia is applied, it is still possible to proceed directly with opening the pulp chamber, but there will be intense pain at the moment of opening. After opening the pulp chamber, the pressure is relieved, and the pain symptoms of pulpitis often can be alleviated. Additionally, medication can be sealed into the root canal, and after controlling the inflammation, the root canal can be filled. During the process of sealing medication and filling the root canal, stimulation of the root apex area may cause discomfort in that area.
Is pulpitis suitable for bloodletting?
Bleeding for pulpitis is useless, and dental treatment is necessary. In the early stages of pulpitis, the pulp can be soothed, which is often seen in reversible pulpitis, and early soothing can relieve pain. Sometimes the pulp can revert to a normal state. If it's the late stage, the tissue pressure inside the pulp is relatively high; in this case, pulp opening can be performed to relieve pressure, and dental treatment is necessary, as bleeding is useless. If the tooth undergoes fundamental treatment promptly in the early stages of pulpitis, the inflammation of the pulp can be controlled in time. Otherwise, further development may lead to inflammation of the root tip. Apical inflammation can sometimes result in abscesses or even facial swelling.
Is the effect of infusion therapy good for pulpitis?
The effectiveness of intravenous therapy for pulpitis is not good. Firstly, pulpitis is an inflammatory pain caused by bacterial infection of the dental nerve. If the inflammation is confined within the root canal and does not spread to cause a systemic gap infection, then the effect of intravenous therapy is poor. Intravenous therapy is just an auxiliary treatment that circulates through the body to reach the tooth tissue, and its effect might not be very noticeable. The primary treatment for pulpitis should involve treating the tooth, removing the infected dental tissue. If the dental nerve is not fully exposed, soothing treatment can be performed, which is also a nerve-preserving treatment method for reversible pulpitis. If the decayed tissue is removed and the dental nerve is exposed, indicating that bacteria have infected the dental nerve, soothing treatment is not possible, and root canal treatment of the tooth is necessary. Only then can the symptoms of pulpitis be alleviated.
Will gingivitis cause gum pain?
Pulpitis is an inflammatory response of the dental pulp tissue caused by a bacterial infection. In the early stages of pulpitis, there is no pain in the gums, as the inflammation is limited to the roots of the teeth, affecting only the pulp within the root canals. This condition can be alleviated through dental treatment, and there are no symptoms in the gums. However, if pulpitis is not treated in a timely manner, the inflammation can progress to the root apex. If not properly drained on time, an abscess can form, meaning the inflammation would break through the gums and begin to discharge pus. This scenario can cause pain in the gums. Therefore, while early pulpitis does not cause gum pain, in the later stages, an abscess in the gums forms, and pain is experienced.
How to brush teeth with cavities
Cavities are a disease caused by bacterial infection of the hard tissues of the teeth, belonging to a type of self-destructive and infectious disease, and cavities need to be treated in a timely manner. When brushing teeth with cavities, it is especially important to brush thoroughly. Fluoride toothpaste can be used to clean each surface of the teeth, including the occlusal, buccal, lingual, and the insides of the teeth. Sometimes it is difficult for the bristles to reach the inside of the teeth, in which case an interdental brush or dental floss can be used to clean these areas to prevent the occurrence of cavities inside the teeth. Besides brushing, it is also necessary to fill the teeth promptly, also known as dental filling.
